Jeeyoung Kim / /


An avid programmer. My interests span from software development to algorithms and mathematics. Challenging real life problems fascinate me. I love working with different levels of abstractions at once.

I was very fortunate to have diverse internship experiences during my university career. It started off as general software engineering - test automation and web development, but I specialized more into infrastructures and big data applications. I spent a year after graduation working on Polychart, a data visualization startup.

At the end of the day, I'm a generalist in heart. I still have much to learn, and I would love to dedicate my passion towards the company and the product that I believe in.
